GREASE-CUP.

To `all toltom may concern:

Be it known that I, GEORGE Lo'rz, citizen of the United States, residingat Ana- A cortes,..in.the, county .offSkagit and State 2 of .Washingtomand useful Improvement in Grease-Cups,'of which the following is aspecification.

r My invention relates to improvementsin have invented a'certain newgrease-.cups such asa-re employed for-forcing greasefintoand throughpassa geways of journal-bearings of machines to lubricate the journalsofshafts of such machines, and the 1 L object of my invention is toprovide a grease- ,cup of a simpleform of construction, a part of whichAmaybe quickly removed, lled `with grease andreplaced in its normal op-Ierativeposition, whereupon the operatlve partsof saidfgrease-cupl maybe actuated to l "causethegrea-se disposed therein to be forced througha passageway thereof to a desired.

point of -lubricatiomand which grease-cup shall have its separable partsso joined that nogrease may escape from the cup except i .through theoutlet passageway thereof.

Iacco'mplish this object by devices illusl. trated in the accompanyingdrawings wherein Figure 1 is a view in side eleva-tion of a structureembodying myl invention; Fig. 2

- is a view of the same in vertical mid-section ternally screw-threadednipple 7 through which extends a concentrically disposed passageway 8which leads to the bottom of the space within said socket 6, and throughwhich passageway 8 grease may be forced ,from such space, said nipple 7beingprovided with a hexagonal portion 9 thus to adapt it to be screwedby means of a wrench into the screw-threaded passageway of a journallbearing thatis to be lubricated by grease emitted from socket 6.

Removably disposed within the socket 6 isa closely fitting invertedcircular cup 10 whose open lower end terminates at a point adjacent tothe bottom of the space within Speoication of Letters Patent.

said socket 6 andthe wall of whose closed upper end is provided with aconcentrically disposed boss 11 through which extends a concentricallydisposed screw-threaded hole within which is rotatably disposed t'hescrew-threaded shank 12 of an integral plunger 13 which is disposedwithin said cup 10 with its periphery closely fitting the inner surfaceof said cup 10 whereby a rotation of said shank 12 may causeisaidplunger 13 to move throughout the space within said cup 10, there beinga handle 14 removably attached to the uppervend portion of said shank 12to facilitate the operation of rotating said shank 12. e L

The circularwall which closes the upper end ofthe cup 10, as shown inFig. 2, is

4extended in its diameter beyond a point registering with the exteriorsurface of the socket 6 and is there provided with an integral sleeve 15which lprojects downwardly in close engagement with said exteriorsurface of said socket v6 thereby increasing the `extent'of joinedsurfaces between the integral parts of the cup 10 and the socket 6 tomake it more diiiicult for grease to leak between such joined surfaces.

As more clearly shown in Fig. 2 there is provided a pin 16 which issecurely disposed to extend through the sleeve 15 and the cylindricalwall of the cup 10 at a point in the upper portion of said sleeve 15,such pin `16 serves as one member of a bayonet-joint the other member ofwhich comprises an .L shaped slot 17 formed in the upper open endportion of the socket 6,\ as more clearly shown in Fig. 4 thus adaptingthe telescopic joint between the socket 6 and the parts of the invertedcup 10 to be locked in an obvious manner when, in the operation ofinserting the cup 10 into the socket 6, the said cup 6 is moved to aposition where the pin 16 will first enter the vertical portion of theslot 17 and then forced to the bottom thereof and thereupon turned in aclockwise direction to cause such pin 16 to be disposed against theblind end of the horizontal portion of said slot 17.

To utilize my invention when embodied in the structure illustrated anddescribed, the nipple 7 is screwed into the lubricating passageway of ajournal bearing that is to be lubricated, in which operation a wrench isapplied to the hexagonal portion 9 and thereupon the cup 10 is removedfrom the socket 6 by rst turning it in a contra-clock- 'wise directionso that the pin 16 may reg.-

ister with the vertical portion of the slot 17- whereupon said cup maybe directly withdrawn from the socket 6 and then the shank 12 is rotatedto move the lunger 13 to a position adjacent to the eng wall of saidcup` 10 and thereupon such cup 10 is filled with grease after which itis again inserted in said socket 6 to assume the position shown 2revolutions impartedY to the shank 12.

In Fig. 5, I have shown a modifiedV form of my invention wherein asocket 18 corresponds to the socket 6 of Figs. 1, 2 and 4 which socket18 'is'provided with a nozzle 19, formed like the nozzle of a syringe,and

within such socket 18 is disposed a cup 20 which corresponds in plan Lofconstruction to the inverted Acup 10 of Figs.y 1, 2 and 3,

and within said cup 20 is a plunger 21 corl so responding to the1plunger 13 of Fig. 2, but attached to said p unger 20 is a planerodlike shank 22 with a handle 23 whichshank 22 and h-andle 23corresponds in function to the shank 12 and handle 14 of Figs. 1, 2 -and3 except that the shank 22 is directly pushed and directly withdrawninstead of being rotated in the operation of moving its attached plunger21.

The structure of Fig. 5, thus embodying contents of said socket carriedmy invention ma serve as a asen when filled withy grease to dsit gsllchgrease places required by pushing inwardly the shank 22 to force theplunger 21 against such grease thus to cause it to be emitted from .thenozzle 19 in.an yobvious manner.

Manifestly, changes may be made in the forms, dimensions and arrangementof parts of my invention without departing from the spiritthereof. l

What I claimis: A grease cup including a socket having a dischargenipple at one end and a bayonet slot in the' other end portion thereof,a

closure for said socket provided with a rsleeve rigidly carried therebyand adapted to embrace the second-named end portion of saidy socket, acup member rigidly carried by said closure and arranged in spacedconcentric relationwith saidsleeve, said cup meinber being of a lengthsubstantially equal to the length of said-socket and adapted to bereceived therein, a portion of the space etween sald sleeve and A saidcup and having one end secured to said sleeve andthe other end securedto said cup said pin "being adapted L"to engage in Asaid bayonet slot,and means for discharging the by said closure. l

In witness whereof, I hereunto subscribe my name this 27th day ofOctober A. D.,
